I am in the process of switching over to Linux as my primary OS, and using Thunderbird and Lightning.

Everything installs just fine. Thunderbird is working, Lightning is working. The problem is, the Mail Folders pane and the Calendar pane are being displayed side by side, rather than integrated into a single pane with the task buttons at the bottom.

I can't find any settings that control this, and it doesn't happen in Windows.

I have the following:

Thunderbird version 2.0.0.6 (20071022)
Lightning 0.7
Kubuntu 7.10

I don't know what other information might be helpful to resolve this (I'm a Linux newbie), so please ask if you have questions.

Yes, I know, and it works correctly on Windows. But in Linux, the Calendar and Folder panes are side by side, rather than one hidden/one visible.

Hi Beckfield,
I had exactly the same problem while using TB (and Lightning) with a shared profile so that I could access the same profile from Win and GNU/Linux. Is it your case? If so then do the following:
1. Download lightning for gnu/linux http://releases.mozilla.org/pub/mozilla ... -linux.xpi2. Download lightning for windows http://releases.mozilla.org/pub/mozilla ... tb-win.xpi3. Rename both .xpi files to .zip and extract them to the same folder (don't worry about overwriting files)
4. Create a new subfolder like this ./platform/Linux_x86-gcc3/components
5. Create a new subfolder like this ./platform/WINNT_x86-msvc/components
6. Move all *.so files from ./components to ./platform/Linux_x86-gcc3/components
7. Move all *.dll files from ./components to ./platform/WINNT_x86-msvc/components
8. Open the file ./install.rdf with text editor and search for em:targetPlatform and change the line to
<em>WINNT_x86-msvc</em>
<em>Linux_x86-gcc3</em>
9. Compress all files in a new zip archive and rename it from .zip to .xpi
10. Install

Thanks for your help. I believe I've followed your steps to the letter, but when I try to install, it fails because "Install script not found." I've looked inside the new zip(xpi) file, and install.rdf is present, and appears to be complete.

Hi,
again, it seems you are encountering the same problems I once did...
Something similar happened to me, and it was because, when I created the zip/xpi file, I compressed the whole folder instead of the files in the folder.
To check if your file is properly created open it with your compression tool and check if what you first see is a folder or a set of folders and files (with install.rdf among them), it should be the second option.
I don't know if I made myself very clear, let me know if you don't understand something.

And I am a recent gnu/linux convert myself, so don't worry much about that

Castaway's trick worked for me using Lightning 0.9. Also, make sure your Windows drive is mounted with the exec option in Linux. If it isn't, the calender pane shows but you cannot do anything with it.
